Bern use two different size charts for their helmets and liners. Make sure you get the same size liner as your Bern helmet for the optimal fit.
Use the 'Single Sizes' chart for all Hard Hat (Brock Foam) liners. Single sized liners will fit all single sized Bern helmets. They will also fit all double sized Bern helmets. For example, a Small liner will fit a Small Bern helmet, an Extra Small/Small Bern helmet or a Small/Medium Bern helmet.
| Single Sizes | Your Helmet Size | ||||||
| XS | S | M | L | XL | XXL | XXXL | |
| cm | 52-53.5 | 54-55.5 | 55.5-57 | 57-59 | 59-60.5 | 60.5-62 | 62-63.5 |
| Inches | 20.5-21 | 21 21.8 | 21.8-22.5 | 22.5-23.2 | 23.2-23.8 | 23.8-24.5 | 24.5-25 |

Use either size chart (depending on how it's labelled on the website or in your helmet) for Thin Shell (EPS) and Zip Mold helmet liners. Double Sized liners will fit all double sized helmets but will also fit single sized helmets. For example, a S/M liner will fit a Small Bern helmet, a Medium Bern helmet or a Small/Medium Bern helmet.
